Installing the Processor
1. Select a convenient, dry, mounting location for the water-resistant processor, a
minimum of 1m (3') from other cables and electronic equipment (Figure 10 or 11).
2. Route the DeviceNet/instrument cable from the processor location to the
network backbone/instrument.
Do not fasten the cable in place at this time.
3. Route the sensor cable to the processor location.
Do not fasten the cable in
place at this time.
4. Hold the processor at the selected location and mark the position of the four
screw holes with a pencil.
NOTE
: If the processor will be mounted on a vertical surface, position the
connectors downward to avoid water seeping into the box.
5. At the marked locations, drill four 3mm or 1/8" holes approximately 10mm (3/8")
deep. At the marked location, drill two 3mm or 1/8" holes approximately 10mm
(3/8") deep.
6. Fasten the processor to the selected mounting surface at the previously-drilled
holes, using the screws supplied.
7.
NMEA 2000
—Connect the DeviceNet cable to the network. Plug the DeviceNet
cable into the port on the processor labeled NMEA 2000.
NMEA 0183
—Wire the instrument cable to the instrument. Refer to the wire
colors and functions below:
Red
VDC+
Black
VDC-
White
A +
NMEA bi-directional
Blue
B -
NMEA bi-directional
Bare
Shield
Plug the instrument cable into the port on the processor labeled NMEA 0183.
8. Plug the sensor into the port on the processor labeled Sensor.
9. Fasten all the cables in place. Coil any excess cable(s) and secure it with cable
ties to prevent damage.
